General stepper motors require leap phase or multi-phase pulse power supply as the driving power supply. The road to invitation is more complicated and the cost is higher. This production
uses a new approach, using the impedance of the two windings of the motor to achieve positive feedback to generate oscillation , achieving a separately excited drive. The circuit only uses 7 parts.
Figure 2-25a is a single-ended drive circuit , and Figure 2-25b is a push-pull drive circuit . In order to obtain the required torque j stepper motor, type 23LM-0304-14 is selected
, its rated voltage is 5. 1V. The rated current is 1.OA and the step size is L 8.
